4. A new macroflora from the South Orkney Islands, Antarctica: evidence of an Early to Middle Jurassic age for the Powell Island Conglomerate

   A macroflora from John Peaks, Powell Island, contains Sagenopteris nilssoniana, Cladophlebis oblonga, Brachyphyllum sp., Elatocladus confertus, and Sphenopteris sp. The macroflora is best correlated with the Botany Bay Group flora, […]

6. Temporal plankton dynamics in an oligotrophic maritime Antarctic lake

   1 The population density, diversity and productivity of the microbial plankton in an oligotrophic maritime Antarctic lake were studied for a 15-month period between December 1994 and February 1996. 2 […]

7. Isolation and characterization of Campylobacter jejuni subsp. jejuni from Macaroni Penguins (Eudyptes chrysolophus) in the subantarctic region

   On Bird Island, South Georgia, albatrosses (n = 140), penguins (n = 100), and fur seals (n = 206) were sampled for Campylobacter jejuni. C. jejuni subsp. jejuni was recovered […]

9. Effects of sea ice cover on the swarming behaviour of Antarctic krill,Euphausia superba

   Much of the distribution range of Antarctic krill, Euphausia superba, is covered by permanent or seasonal sea ice. Sea ice extent has been implicated as a major factor affecting reproductive […]

10. Physical oceanographic conditions to the northwest of the sub-Antarctic Island of South Georgia

    Ocean physics is a key aspect of the operation of island ecosystems, yet the hydrodynamics is sometimes poorly understood. A high-resolution oceanographic survey to the north of South Georgia identified […]

11. State-dependent fertility in pinnipeds: contrasting capital and income breeders

    1. The study tested the hypothesis that the occurrence of pregnancy in mammals that are capital breeders will be most closely related to state variables that are indices of food […]

12. Skin temperatures during free-ranging swimming and diving in Antarctic fur seals

    This study tests the hypothesis that an endothermic homeotherm should minimise heat flux in cold polar waters by minimising skin temperature. Temperature variability was measured at the surface of the […]
